Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a special loading platform for hepatobiliary surgery. Background Art

[0002] Hepatobiliary surgery mainly studies major diseases that seriously threaten the health of Chinese people, such as hepatocellular carcinoma, hepatobiliary stones, post-hepatitis cirrhosis and acute liver failure caused by severe hepatitis. It is a common diagnosis and treatment subject in medical institutions. Puncture cell culture is a common examination item to determine and exclude cancer. During the culture process, the puncture cells collected in the early stage need to be scraped on a glass slide to make a culture specimen, and then follow-up observation and testing are carried out after a period of culture.

[0003] At present, when conducting laboratory tests on hepatobiliary surgical specimens, a microscope is usually used for continuous observation. The sample is dropped on a glass slide, and after a cover glass is put on, it is placed on the microscope slide for observation. For example, a hepatobiliary surgical specimen processing device published with announcement number "CN115979770B" replaces the direct clamping method of the prior art by the pressing clamp by the fixing method of the glass slide using the suction column, thereby avoiding the phenomenon of the pressing clamp pushing the cover glass during implementation.

[0004] However, in actual operation, the slide needs to be placed directly under the microscope to facilitate observation by the staff. The placement of the above-mentioned equipment is entirely dependent on manual operation by the staff, which can easily lead to deviations in the placement position. When the slide is taken later, tools are required to take it. Manual picking can easily cause the slide to tilt, which may cause the sample to drip, causing contamination and making it inconvenient to take the sample. Summary of the invention

[0005] The object of the present invention is to provide a special stage for hepatobiliary surgery to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a special stage for hepatobiliary surgery, comprising a microscope and a slide stage, a side of the microscope is provided with a lens barrel height adjustment knob, the lens barrel height adjustment knob comprises a coarse focusing screw and a fine focusing screw, a power switch is provided on the surface of the microscope, a pressure frame is provided on the front of the microscope, a positioning component for positioning a slide is provided on the slide stage, an auxiliary component for conveniently taking the slide is provided on the slide stage, and the positioning component comprises a cylinder, a worm, a knob, a worm gear and a clamping portion.

[0007] Preferably, the auxiliary component includes a support plate, which is plugged into the glass stage, a through hole is provided on the top of the cylinder, a linkage gear is rotatably installed on the inner wall of the cylinder, a vertical groove and a transverse groove are provided on the inner wall of the cylinder, the transverse groove and the vertical groove are connected to each other, a baffle is slidably installed on the inner side of the vertical groove, a vertical rack is fixed to the bottom of the baffle, a transverse rack is fixed to the surface of the vertical rack, a gear ring is fixed on the side of the linkage gear away from the cylinder, a connecting rod is fixed on the side of the linkage gear close to the gear ring, a spiral groove is provided on the surface of the connecting rod, a sliding rod is slidably installed on the inner side of the spiral groove, one end of the sliding rod away from the connecting rod is fixed to a slider, a moving groove is provided on the inner wall of the cylinder, the slider is slidably installed on the inner side of the moving groove, a return spring is fixed on the inner side of the moving groove, The end away from the moving groove is fixed to the slider. When the pallet is inserted into the glass slide table and extends into the cylinder, the pallet contacts the slider and pushes the slider to move together. The slider drives the slide rod to slide in the spiral groove on the surface of the connecting rod, causing the connecting rod to rotate, thereby driving the connecting rod and the linkage gear to rotate. At this time, the vertical rack is in a state of meshing with the linkage gear. The linkage gear can control the vertical rack to move the baffle downward, and the baffle moves downward along the vertical groove. When the baffle moves to the position of the horizontal groove, the horizontal rack fixed on the surface of the vertical rack engages with the gear ring, thereby controlling the baffle and the vertical rack to move to the side away from the center of the through hole, so that the glass slide placed on the baffle falls on the pallet. At this time, you only need to release the pallet, and the reset spring can drive the slider to reset, and the slider can contact the pallet to reset, which is convenient for the staff to take the slide without causing pollution to the slide.

[0008] Preferably, a driven part is provided on the surface of the vertical rack, and the driven part includes a groove, the groove is opened on the surface of the vertical rack, a sliding tooth is slidably installed on the inner side of the groove, a connecting spring is fixed on the inner side of the groove, and the end of the connecting spring away from the groove is engaged with the sliding tooth.

[0009] Preferably, the driven parts are provided with two groups, one group of the driven parts is arranged on the surface of the vertical rack, and the other group of the driven parts is arranged at the bottom of the transverse rack. When the sliding teeth on the vertical rack are meshed with the linkage gear, the linkage gear contacts the sliding teeth, and cooperates with the connecting spring to control the sliding teeth to slide up and down, and the vertical rack will not move downward. At this time, as the transverse rack is meshed with the gear ring, the vertical rack can be controlled to move out of engagement through the transverse rack. When the linkage gear rotates in the opposite direction, the transverse rack drives the vertical rack to reset. When the sliding teeth at the bottom of the transverse rack are meshed with the gear ring, the teeth of the gear ring contact the sliding teeth, causing the sliding teeth to slide left and right. At this time, the transverse rack cannot continue to move, and is re-engaged with the linkage gear through the vertical rack, so that the vertical rack can be controlled to drive the baffle to reset upward.

[0010] Preferably, the cylinder passes through the glass stage and is rotatably connected to the glass stage, a worm gear is fixed to the surface of the cylinder, the worm is meshed with the worm gear, the knob is fixed to the worm gear, and the clamping portion is arranged on the top of the glass stage and the cylinder. By turning the knob, the worm gear is driven to rotate, and the cylinder can be driven to rotate through the worm gear, thereby controlling the clamping portion to center and clamp the glass slide placed on the top of the cylinder.

[0011] Preferably, the clamping portion includes an arc-shaped groove, which is provided at the top of the cylinder, and a guide groove is provided at the top of the glass slide, an L-shaped rod is slidably installed on the inner side of the guide groove, a fixing plate is fixed to the end of the L-shaped rod away from the guide groove, and an insertion rod is fixed to the bottom of the L-shaped rod, and the insertion rod is inserted into the inner side of the arc-shaped groove. When the cylinder rotates, since the L-shaped rod is limited by the guide groove, the cylinder can contact the insertion rod through the arc-shaped groove provided on its top, thereby pushing the insertion rod to move along the guide groove with the L-shaped rod, thereby controlling the fixing plate to fix or release the glass slide.

[0012] Preferably, a scroll spring is fixed to the surface of the cylinder, and one end of the scroll spring away from the cylinder is fixed to the inner wall of the glass carrier, and one end of the worm gear away from the knob abuts against a push plate, and a connecting groove is provided on the side of the glass carrier, and a moving block is slidably installed on the inner side of the connecting groove, and a tension spring is fixed to the inner side of the connecting groove, and one end of the tension spring away from the connecting groove is fixed to the moving block, and the moving block is penetrated by the worm and rotationally connected with the worm. When the support plate is inserted into the glass carrier, the support plate can abut against the push plate, so that the worm gear and the moving block move to the side away from the worm gear, so that the worm gear and the worm gear are disengaged. At this time, the cylinder can rotate in the opposite direction and reset under the action of the scroll spring, and the clamping part is controlled to loosen the fixation to the glass slide. At the same time, it can be ensured that the insertion hole provided on the surface of the cylinder can face the support plate, thereby ensuring that the support plate can be inserted.

[0013] Preferably, an insertion hole is provided on the surface of the cylinder for the support plate to be inserted into.

[0014] Compared with the prior art, the present invention provides a special stage for hepatobiliary surgery, which has the following beneficial effects:

[0015] 1. The special stage for hepatobiliary surgery, through the auxiliary components and positioning components, when the slide needs to be taken after the observation, it is only necessary to insert the pallet into the stage, and the pallet can resist to separate the worm and the worm wheel, and the clamping part can be controlled to release the fixation of the slide, and with the insertion of the pallet, the baffle moves downward with the slide, and the two groups of baffles can be controlled to move away from each other, and the slide on the top of the baffle can fall on the pallet, and the slide can be taken out by simply pulling out the pallet, which is easy to use.

[0016] 2. The dedicated stage for hepatobiliary surgery has a positioning component. After placing the glass slide on the top of the cylinder, the worm can be turned to control the clamping part to clamp and position the glass slide, ensuring that the glass slide can be centered and directly under the microscope lens, making it convenient for staff to observe.

[0017] 3. For the special stage for hepatobiliary surgery, when the pallet is inserted into the glass slide, the pallet can come into contact with the push plate, so that the worm and the moving block move to the side away from the worm wheel, so that the worm and the worm wheel are out of meshing state. At this time, the cylinder can rotate in the opposite direction to reset under the action of the scroll spring, and the clamping part is controlled to loosen the fixation of the glass slide. At the same time, it can be ensured that the insertion hole opened on the surface of the cylinder can face the pallet, ensuring that the pallet can be inserted. BRIEF DESCRIPTION OF THE DRAWINGS

It is worth noting that the pressure frame 14 is composed of a spiral rod and a pressure plate. The pressure plate is slidably connected to the body of the microscope 1. The pressure plate can be controlled to move up and down by rotating the spiral rod, thereby resisting the glass stage 2. The coarse focusing screw 131 and the fine focusing screw 132 are used to adjust the focal length of the microscope 1 and control the height of the lens barrel. This is an existing known technology and has existing products. It is not the main innovative part of this application, so it is not elaborated on in detail.

[0027] The auxiliary component 4 includes a support plate 41, which is plugged into the glass stage 2. A through hole 42 is provided on the top of the cylinder 31. A linkage gear 43 is rotatably mounted on the inner wall of the cylinder 31. A vertical groove 44 and a horizontal groove 45 are provided on the inner wall of the cylinder 31. The horizontal groove 45 and the vertical groove 44 are connected to each other. A baffle 46 is slidably mounted on the inner side of the vertical groove 44. A vertical rack 47 is fixed to the bottom of the baffle 46. A horizontal rack 48 is fixed to the surface of the vertical rack 47. A gear ring 49 is fixed to the side of the linkage gear 43 away from the cylinder 31. A connecting rod 410 is fixed to the side of the linkage gear 43 close to the gear ring 49, and a spiral groove 411 is provided on the surface of the connecting rod 410. A sliding rod 412 is slidably installed on the inner side of the spiral groove 411. The end of the sliding rod 412 away from the connecting rod 410 is fixed to a slider 413. A moving groove 414 is provided on the inner wall of the cylinder 31. The slider 413 is slidably installed on the inner side of the moving groove 414. A return spring 415 is fixed to the inner side of the moving groove 414. The end of the return spring 415 away from the moving groove 414 is fixed to the slider 413. When the support plate 41 is inserted into the glass stage 2 and extends into the cylinder 31, the support plate 41 abuts against the slider 413 and pushes the slider 413 to move together. The slider 413 slides the slide bar 412 in the spiral groove 411 on the surface of the connecting rod 410, so that the connecting rod 410 rotates, thereby driving the connecting rod 410 and the linkage gear 43 to rotate. At this time, the vertical rack 47 is in a state of meshing with the linkage gear 43. The linkage gear 43 can control the vertical rack 47 to move downward with the baffle 46, and the baffle 46 moves along the vertical groove 44 Moving downward, when the baffle 46 moves to the position of the horizontal groove 45, the horizontal rack 48 fixed on the surface of the vertical rack 47 engages with the gear ring 49, thereby controlling the baffle 46 and the vertical rack 47 to move to the side away from the center of the through hole 42, so that the glass slide placed on the baffle 46 falls on the support plate 41. At this time, you only need to release the support plate 41, and the reset spring 415 can drive the slider 413 to reset, and the slider 413 can resist the support plate 41 to reset, which is convenient for the staff to take the slide without causing contamination to the slide.

[0028] A follower part 5 is provided on the surface of the vertical rack 47, and the follower part 5 includes a groove 51. The groove 51 is opened on the surface of the vertical rack 47, and a sliding tooth 52 is slidably installed on the inner side of the groove 51. A connecting spring 53 is fixed on the inner side of the groove 51, and the end of the connecting spring 53 away from the groove 51 is meshed with the sliding tooth 52.

[0029] Specifically, two groups of driven parts 5 are provided, one group of driven parts 5 is provided on the surface of the vertical rack 47, and the other group of driven parts 5 is provided at the bottom of the horizontal rack 48. When the sliding teeth 52 on the vertical rack 47 are meshed with the linkage gear 43, the linkage gear 43 abuts against the sliding teeth 52, and cooperates with the connecting spring 53 to control the sliding teeth 52 to slide up and down, and does not cause the vertical rack 47 to move downward. At this time, as the horizontal rack 48 is meshed with the gear ring 49, the horizontal rack 48 can be used to move the vertical rack 47 downward. 8 controls the vertical rack 47 to move out of meshing. When the linkage gear 43 rotates in the opposite direction, the horizontal rack 48 drives the vertical rack 47 to reset. When the sliding teeth 52 at the bottom of the horizontal rack 48 are meshed with the gear ring 49, the teeth of the gear ring 49 abut against the sliding teeth 52, causing the sliding teeth 52 to slide left and right. At this time, the horizontal rack 48 cannot move further, and the vertical rack 47 is meshed with the linkage gear 43 again, so that the vertical rack 47 can be controlled to drive the baffle 46 to reset upward.

[0030] The cylinder 31 passes through the glass stage 2 and is rotatably connected to the glass stage 2. A worm gear 34 is fixed to the surface of the cylinder 31. The worm 32 is meshed with the worm gear 34. The knob 33 is fixed to the worm 32. The clamping portion 35 is arranged on the top of the glass stage 2 and the cylinder 31. By turning the knob 33, the worm 32 is driven to rotate, and the cylinder 31 can be driven to rotate through the worm gear 34, thereby controlling the clamping portion 35 to center and clamp the glass slide placed on the top of the cylinder 31.

[0031] The clamping portion 35 includes an arc groove 351, which is opened at the top of the cylinder 31. A guide groove 352 is opened at the top of the glass stage 2. An L-shaped rod 353 is slidably installed on the inner side of the guide groove 352. A fixing plate 354 is fixed to the end of the L-shaped rod 353 away from the guide groove 352. An insertion rod 355 is fixed to the bottom of the L-shaped rod 353. The insertion rod 355 is inserted into the inner side of the arc groove 351. When the cylinder 31 rotates, since the L-shaped rod 353 is limited by the guide groove 352, the cylinder 31 can contact the insertion rod 355 through the arc groove 351 opened on the top of itself, thereby pushing the insertion rod 355 to move along the guide groove 352 with the L-shaped rod 353, thereby controlling the fixing plate 354 to fix or loosen the glass slide.

[0032] An insertion hole 10 is provided on the surface of the cylinder 31 for inserting the support plate 41, a spiral spring 11 is fixed on the surface of the cylinder 31, and the end of the spiral spring 11 away from the cylinder 31 is fixed to the inner wall of the glass stage 2, and the end of the worm 32 away from the knob 33 abuts against the push plate 6, and the push plate 6 is slidably installed on the inner wall of the glass stage 2, and a connecting groove 7 is provided on the side of the glass stage 2, and a moving block 8 is slidably installed on the inner side of the connecting groove 7, and a tension spring 9 is fixed on the inner side of the connecting groove 7, and the end of the tension spring 9 away from the connecting groove 7 is fixed to the moving block 8. The moving block 8 is penetrated by the worm 32 and is rotationally connected to the worm 32. When the support plate 41 is inserted into the glass slide 2, the support plate 41 can abut against the push plate 6, so that the worm 32 and the moving block 8 move to the side away from the worm gear 34, so that the worm 32 and the worm gear 34 are out of meshing state. At this time, the cylinder 31 can rotate in the opposite direction and reset under the action of the spiral spring 11, and the clamping part 35 is controlled to loosen the fixation of the glass slide. At the same time, it can ensure that the insertion hole 10 opened on the surface of the cylinder 31 can face the support plate 41, ensuring that the support plate 41 can be inserted.

[0033] Based on the above embodiment, first place the slide on the top of the slide table 2 so that the slide is on the cylinder 31, drop the sample on the slide, and after dropping, place the cover glass on the slide, slowly turn the knob 33, the knob 33 drives the worm 32 to rotate, thereby driving the worm gear 34 to drive the cylinder 31 to rotate, and since the L-shaped rod 353 is limited by the guide groove 352, the cylinder 31 can contact the insertion rod 355 through the arc groove 351 opened on its top, thereby pushing the insertion rod 355 to move along the guide groove 352 with the L-shaped rod 353, thereby controlling the fixing plate 354 to fix the slide, and at the same time can push the slide to the center, ensuring that the slide is directly below the lens of the microscope 1, and the staff observes through the microscope 1.

[0034] After the observation is completed, the support plate 41 is inserted into the glass slide 2. When the support plate 41 is extended into the glass slide 2, it abuts against the push plate 6, so that the worm 32 and the moving block 8 move to the side away from the worm gear 34, so that the worm 32 and the worm gear 34 are out of meshing state. At this time, the cylinder 31 can be rotated in the opposite direction and reset under the action of the spiral spring 11, and the clamping part 35 is controlled to loosen the fixation of the glass slide. At the same time, it can ensure that the insertion hole 10 on the surface of the cylinder 31 can face the support plate 41, ensuring that the support plate 41 can be inserted.

[0035] As the support plate 41 continues to be inserted, the support plate 41 extends into the cylinder 31, and the support plate 41 abuts against the slider 413 to push the slider 413 to move together. The slider 413 brings the slide bar 412 to slide in the spiral slide groove 411 on the surface of the connecting rod 410, so that the connecting rod 410 rotates, thereby driving the connecting rod 410 and the linkage gear 43 to rotate. At this time, the vertical rack 47 is in a state of meshing with the linkage gear 43. The linkage gear 43 can control the vertical rack 47 to move downward with the baffle 46, and the baffle 46 moves downward along the vertical groove 44. When the baffle 46 moves to the position of the horizontal groove 45, the horizontal rack 48 fixed on the surface of the vertical rack 47 engages with the gear ring 49, thereby controlling the baffle 46 and the vertical rack 47 to move to the side away from the center of the through hole 42, so that the glass slide placed on the baffle 46 falls on the support plate 41. At this time, you only need to release the support plate 41, and the reset spring 415 can drive the slider 413 to reset, and the slider 413 can resist the support plate 41 to reset, which is convenient for the staff to take the slide without causing contamination to the slide.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
